How to choose the best hollow anchor bar for corrosion protection?
Time:2021-12-11From:sinorock View:
In engineering applications, the biggest influence on the service life of self drilling hollow anchor bolts is stratum environment. Especially when it is used in sea area or close to the coastline, where the environment is more aggressive. Therefore, you should select hollow anchor rods for corrosion protection in aggressive environments. Next, I will introduce how to choose the best suitable anti-corrosion anchor bar in different application environments.1. Non-aggressive Environment
For non- aggressive environments, the cement grout can also protect anchor bar body from corrosion. Research shows that different stratum or application structures have corresponding requirements on the grout thickness if they want to achieve corrosion resistance. For example, when used as a compressive pile, the grout thickness should be at least 20mm; when used in soil, the thickness should be at least 20mm; when used as a tensile pile the thickness should be at least 30mm. Be sure, this is only the minimum value. At the same time, it should be noted that the crack width should not be too large, otherwise it will greatly affect the anti-corrosion performance.
2. Aggressive Environment
Aggressive environment is complex and diverse, Sinorock provides a variety of anti-corrosion anchors to meet different needs of customers.
3. Stainless steel hollow anchor bolt
Stainless steel hollow anchor bolt is made of stainless steel, with better anti-corrosion performance, and it can resist the corrosion of air and chemical media. In addition to the convenient construction characteristics of self drilling hollow anchor rods, stainless steel anchor rods also have excellent weldability, high strength and wear resistance.

5. Epoxy coating anchor bolt
The epoxy resin is sprayed on the bolt surface by electrostatic spraying. Sinorock epoxy coating products are mainly based on EN 13438, and the service life is not less than 30 years. Epoxy coating anchor bolt is suitable for occasions where stratum and groundwater contain sulfides and chlorides, corroded by seawater, and environments with stray currents or corrosive medium.
